The Plug-in Object

The plug-in object is Interface Builder’s initial entry point into your plug-in and is represented by the IBPlugin class. You must provide a subclass of this object in your plug-in and configure it as the primary class of your plug-in bundle. Your plug-in object has one critical responsibility: provide the list of nib files identifying the objects your plug-in represents. Beyond that, you use the plug-in object to provide support for other features of your plug-in. For example, you use the plug-in object to implement a preferences window or customize objects as they are dragged out of the library window.

The following sections describe the tasks you can perform from your custom plug-in object. For additional information about the methods of the IBPlugin class, see IBPlugin Class Reference.
